you follow electrostatic discharge safety measures and antistatic practices. See “Performing
Electrostatic Discharge and Static Prevention Measures” on page 98 .

Identify and Remove a Faulty Processor
Caution - Be careful not to touch the processor socket pins. The processor socket pins are very
fragile. A light touch can bend the processor socket pins beyond repair.
Caution -
Whenever you remove a processor, replace it with another processor and reinstall the
processor heatsink; otherwise, the server might overheat due to improper airflow. See “Install a
Processor” on page 177 .
